What are you using to measure salinity/SG ?

[gobytron]

I use a regularly calibrated Vertex refractometer.

I actually tested my top up water and it was 0 on the same refractometer.

To clarify, the Dino and Cyano happened due to the salinity increase, and now, after 3 30 gallon water changes (it's a 95 gallon tank with 60 gallon sump) we're back to 1.24-1.25 and the dino's are all gone with very little cyano in some lower flow spots remaining.

salinity is 1.6? salinity of NSW is like 35... So you essentially have a fresh water tank now?

[Bblinks]

thought fresh water is at 1? 1.6 is like triple the natural salinity...

I thought he meant maybe his SG went up to 1.060 from 1.025 or whatever he normally keeps it at.

do u dose as well? I noticed mine climbed from 1.025 to 1.031. only thing I could put it down to was dosing.
I think specifically it was magnesium. I was trying the whole add tons of mag and hope the algae will die off trick... never got it to work.
